MAXIM ZAVARKIN, OF EAST BBIMFIELD, MASSACHUSETTS.

CONCRETE TIE.

Application filed Januaryr 2, 191B.

To c/Z whom z't may concern:

Be it known that I` MAXIM ZAVARKIN, a citizen of Russia. resident oi East Brimiield, county of Hampden, and State of Massachusetts, have invented certain new and useful Improvements in Concrete Ties, of' which the following is a specification.

This invention relates to improvements in railroad ties and particularly to those constructed principallyT of concrete.

The principal object of [he invention is to provide a tie relatively light, exceptionally strong and of extreme durability.

A further object is to provide a tie or sleeper formed of concrete molded into shape, whereby the cost oi construction is reduced, and finally, to provide in the ends of the tie, metallic inserts for receiving rail holding devices, such inserts being connected by reinforcing rods passing longitudinally through the lower side of the tie.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanyingT drawing, forming a material part of this specification, and in which:-

Figure 1 is a top plan view of a tie made in accordance with the invention, parts being shown in section in order to show the interior construction.

Fig. 2 is a side view of the same.

Fig. 3 is an enlarged transverse sectional view taken on line 3-3 of Fig. 2.

Fig. 4 is a perspective view showing one of the inserts, and securing elements embedded in the tie, and

Fig. 5 is a side elevational view showing a modified form of insert.

The tie, as shown in Figs. l and 2 is substantially rectangular, comprising a pair of oppositely disposed spaced heads 10 integrally connected by a central element11,nar rower than the heads which are formed with exterior beveled surfaces 12, thereby rendering it easy to raise and remove the same from the ground by a bar.

In the heads 10 are pairs of metallic reinforcing inserts, the pairs being spaced to suit the distance between the rails, and the members of each pair so spaced that the bolts, entered therein. engage upon either side of the rail ange.

The upper element 14 of the insert is set below the upper surface of the tie, parallel therewith and is provided with a plu- Specication of Letters Patent.

rality of threaded openings l5 for bolts, screws or like securing means.

Engaged with the ends of the upper element 14 are angularly disposed braces 16, joined at their lower end by a lower element 17 and having therebetween a center bar 18, forming through spaces 19 which obviously will become filled with cement in the process of molding, serving to bind and hold the inserts solidly within the heads of the tie. These inserts are further held in the material of the tie by means of rods 20 fitted to openings 21 formed in the lower element 17 of the insert. the entire structure being thus firmly bound together.

The openings 15 in the top of the inserts register with openings 22, in the top of the tie through which securing bolts may be entered.

In Fig. 5 is shown a modification of insert, the same being formed in separate sections, the upper of which has an element 25 from which depend arms 26 and a central stem 27. the latter of which is fitted between guides 28 formed with the bottom element 30 of the lower insert section. and is also provided with openings 31 for receiving the binding rods 20, threaded screw holes passing through the top element 25 in the manner before described.

The depending arms 2G of the upper section are formed with serrations 33, engageable with similar serrations 34, formed in the upper arms 35 of the lower section 30, so that when the two sections are in intimate relation, any weight which may be placed upon the upper section 25 will be transmitted by the serrations to the lower section in an obvious manner, it being evident that the parts must be assembled before pouring the cement.

From the foregoing it will be seen that a strong and durable form of tie has been disclosed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a concrete tie, the combination with a rigid body having enlarged heads receptive of track-rails and an integrally formed connecting element therebetween, of beveled surfaces formed at the ends of said tie, metallic inserts arranged in airs at the ends of said tie, and a pair o tie rods eX- tending between said inserts embedded in the concrete.

2. In a concrete tie, the combination with an elon ated body suited to reoei'vetruelrails, o spacedwpairs of reinforcing metallic inserts nenr the ends of said body, reinforcing inserts being comprised of two sfepgrpte geotions, `the upper section lfiffrvlig a. central stem, a pair of upright gin es formed with the lower seotion reqeptive of said stein and paire of integral rigid nrms formed with each section on adjacent portions, and il'ltelenggtging oorrugntions on the contracting snrfaees of said arms.

In a concrete tie, the combination with thge body `thereof, .of :i T shaped upper ele'- nient having angularly disposed depending eide arms, a lower element having out# wardly extending arms, a plurality of corrugaitions forined upon the adjacent sur- ;Eaees of all of `said arms, and a pair of guides -formed on said lower element adapted toiinake Contact with the central stem 0f Said'T'eleinent n i 4. In combination, a` rigid body eo1npoedof two sections, one section having Vopposlitely-:inelined Hides formed upon Atheir inner edges with oorrugutions, un'int/egral pair of central upwaidlyextending portione, a `-Second rigid body formed with oppositely-inclined SideS formed with corrugutions upon their outer edges engaging udjusltably the corrugations on the first body, und having a depending centrail airm slidably mounted between the pair of upwardlyextending portions.

ln testimony whereof I have niixed my signature.
